Detailed Description

The field affects elements inside its area of effect defined by a shape list. The force is at the maximum inside the shape. Optionally it diminishes by distance from the border of the shape. An exponent can be defined to alter the falloff from the border. No area shape equals a point force field.

The force is applied either radially from the center, linearily along direction or vertex like swirrling around the direction. Negative force creates a force field attracting elements instead of repelling them. For vortrex type positive force swirls around counter-clock-wise while negative force swirls around clock-wise. The force direction is relative to the force field orientation allowing to alter the force direction without needing to adjust the area of influence shape which is oriented to the force field orientation itself. The force is measured in newton and can be applied directly, by surface or by volume.

Directly applied the force affects all elements exactly the same. This can be used for example for paranomal effects where the shape of elements is unimportant.

Applied by surface the set force is Newton per Meter-Squared. The area used to calculate the force is the surface area exposed to the force direction. This can be used for wind or water forces pushing against exposed surface area. Physics modules are free to approximate this surface area as they see fit.

Applied by volume the set force is Newton per Meter-Cubic. The volume used to calculate the force is the real or representative volume of elements. For elements having a shape the volume is the volume of all space occupied by all shapes combined. For particles the shape is usually a sphere roughly representing the particle. This can be used for field effects like magentism which do not care about exposed surface area only the volume they can affect. Physics modules are free to approximate this volume as they see fit.

The force direction and force can be subject to fluctuation to make the force field more life-like. Physics modules alter the applied force direction and force strength randomly over time.

Force fields can be disabled avoiding the need to remove and add them to the world.
